NOZZLE FOR VACUUM CLEANERS. Application filed April 30, 1924. Serial No. 710,015.

This invention relates to certain new and Figure 4 is a vertical cross-sectional View useful improvements in nozzles for vacuum taken on line VIVI of Fig. 3. cleaners and has for its primary object to Referring more in detail to theaccomprovide a nozzle or head having a casting or panying drawings, and particularly to Figs.

5 brush support positioned centrally and lon- 1 and 2 there is illustrated a Vacuum nozzle gitudinally of the air inlet or suction opening embodying a head A embodying a rear wall of the nozzle to provide relatively narrow B designed for supporting a motor and a or restricted inlet air conduits at each side dust collecting receptacle or bag that is in of the brush support to increase the force of communication with the exhaust opening 10 suction or vacuum through the nozzl e or C in the rear wall B. head for delivery through the fan housing The rear wall B of the nozzle head supto' the dust collector bag or receptacle. ports the nozzle at the forward side thereof A further object of the invention is to that includes a front wall D and a rear construct a nozzle for vacuum cleaners of wall E, the front wall D being provided 15 the type above set forthwherein the casting with a relatively large opening F to facilior brush support designed to provide spaced ta'te the attachment of special cleaning deair inlets or conduits is fashioned in a vices as .is customary with vacuum cleaner manner to permit the mounting of stationnozzles of this general type. A casting or my spaced brush elements. brush support extends longitudinally of the It is also an object of the present invennozzle head and is disposed between the tion to construct a vacuum cleaner nozzle of walls D- and E and embodies a skeleton body the above type that employs stationary brush having a front wall .10 lying parallel with elements with devices disposed between the and spaced from the front wall D of the brush elements to engage a carpet or other nozzle head, and a curved rear wall 11 that 25 surface to be cleaned to control the amount is curved coincident to the curvature of of pulling movement or strain upon the carthe rear wall E of the nozzle head, the walls pet or surface during use of the vacuum 10 and 11 merging into a single centrally cleaner. positioned Wall extension 7 that terminates With the above general objects in View adjacent the lower edges of the nozzle head 30 and others that will become apparent as openings C and F. The walls 10 and 11 of the nature'of the invention is better underthe casting merge together at the point 3 stood, the same consists of the novel form, and then continue upwardly and rearwardly combination and arrangement of parts herein the single wall extension 7 as clearly inafter more fully described, shown in the shown in Fig. 2. The lower wall G of the 35 accompanying drawings and claimed. brush supporting casting has longitudinally 99 In the drawings, wherein like reference extending channeled portions or grooved characters designate corresponding parts seats H that support stationary brush backthroughout the several views. ings 4 that carry depending bristle portions Figure 1 is a front elevational view, partly 45 that slightly project below the bottom broken away of a vacuum cleaner nozzle entrance opening I at the lower end of the constructed in accordance with the present nozzle head. The mounting of the brush invention with the stationary brush elements supporting casting with respect to the walls removed and showing the devices for hold- D and E of the nozzle head provide reing a carpet upon the floor during cleanstricted air entrance openings 1 and 2 at 5 ing thereof, each side of the casting that communicate 100 Figure 2 is a vertical cross-sectional view with restricted or narrow conduits 5 and 6 taken on line II-II of Fig. 1 showing the that extend upwardly between the walls casting or brush supporting bracket posiof the nozzle head and the casting through tioned centrally of the vacuum nozzle dethe single outlet or exhaust opening C. fining spaced reduced air inlet conduits, 0 reduce pulling strains on a carpet ig. 3 is a front elevational view partly or like article being cleaned due to the broken away of another form of the invensuction in the nozzle 'head, devices are astion with the brush element at one side resociated with the bottom wall G of the I moved and fragmentarily illustrated at the brush-supporting casting and include arched other side, and formations as shown in Figs. 1 and 2 having side walls 8 curved transversely of the brush supporting castin with the lower reduced ortions 8 lying ush with the nozzle openmgs 1 and 2, the side walls 8" ofthe arched portions 8 defining spaced pockets 9 while the lower edges 8 of the arched portions contact the carpet to hold the same in a substantially fiat condition against the power of suction in the nozzle head. The arched portions 8 are enlarged at their upper ends and merge into the lower edge walls of the brush receiving pockets H and afford effective means for the purposes intended.

Another form of the invention is shown in Figs. 3 and 4, in which the front wall 10 of the brush supporting casting is disposed at an angle to the front wall D of the nozzle head while the rear wall 11 is curved away from the rear wall E of the head. The single extension v wall 7 is disposed at an angle to the rear wall E resulting in increasing areas in an upward direction in the conduits 5 and 6. In lieu of formations 8 as shown in'Figs. land 2 for reducing ipullin strains upon the carpet or other sur ace being cleaned, the bottom G of the brush supporting casting carries depending ribs 8' arched downwardly from the points 8 and terminating in spaced bottom feet 8 lying in the same plane as the lower ends of the head walls D and E while the brush elements 4 project beneath the same.

While there are herein shown and described the preferred embodiments of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

\Vhat is claimed as new is In a vacuum cleaner nozzle, a nozzle head, a brush supporting casting disposed centrally within the nozzle head dividing the same into spaced air inlet conduits, spaced arched members depending from the longitudinal center of the casting to the plane occupied by the outer edges of the inlet conduits to reduce pulling strains on the article being cleaned and a stationary brush at each side of the casting positioned laterally of the conduit and at opposite sides of the depending arched members.

In testimony whereof I affix my signature.
